What it delivers
The Bosch 7738007417 8.5 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 8.5 kW. Its listing gives a maximum flow of 1.5 GPM.
At a 45°F rise (mild inlet water to a 120°F set point) it holds about 1.3 GPM, less than one 2 GPM shower; in winter, at a 70°F rise, about 0.8 GPM, less than one 2 GPM shower. Check your house in the planner.
At 240 volts 8.5 kW is about 35 amps. Whether your panel can carry it alongside heating and cooking loads is an electrician's call.
